Reference: The Venus, 2(2): 48
Type genus: Okadaia Baba, 1930
Remarks: Full description, and declared "nov.

cited Okadaiidae as from the latter publica-
tion, and treated it as a junior synonym of
BOUCHET&ROCROI
Vayssiereidae. The latter, although the junior
synonym, is prevailingly used over Okadaiidae;
however, as this is a rarely used
family name, which includes only four de-
scribed species, priority should apply.
